4. Draw Parallel Lines — On the top half of the paper, left of the transversal, place a point at the intersection of a blue line and the left hand crease. Your choice which line is chosen. Label point as point A.

5. Count down from pt. A ______ number of lines. Follow this line to the right hand crease and place another point. Label the right hand point as point B. Use ruler to connect points to form line AB.

6. On the bottom half of the paper, left of the transversal, place a point at the intersection of a blue line and the left hand crease. Label point as point C.

7. Count down the same number of lines that you chose on step 5. Follow this line to the right hand crease and place another point. Label the right hand point as point D. Use a ruler to connect points to form line CD.

8. Number angles 1-4 down the left hand side of the transversal and 5-8 down the right hand side of the transversal.

9. The angles in the gray areas are called exterior angles because they are outside of the parallel lines.

The angles in the white area are called interior angles because they are between the parallel lines.

10. Use scissors to cut along the transversal, both parallel lines, and the hamburger crease.

11. Using the cut out angle pieces fill in the chart by determining which angles are congruent.
